IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 156,8 13, dated November 10, 1874 application filed september 5, 1874.

To all whom it may concern:

Be it known that I, EDWARD PALMIE, of the city of Brooklyn, in the county of Kin gs and State of New York, have invented certain Improvements in Stoves and Heaters, of which the following is a specication:

This invention relates to stoves and heaters, having for its object to improve the construction of the same 5 and consists in the combination of the aslrpiece with ange and socket, and the grate with the lire-bar; and the combination of the foot-piece and seats, with perforations, with the ash-piece, mantel, and tlue, as will be hereinafter more fully set forth and pointed out by the claims.

In the annexed drawings, Figure l represents a central vertical section of the stove constructed with my improvements. Fig. 2 is a detached top view of the bottom or foot plate ofthe same. Fig. 3 is a detached top view of the ash-pit piece of the same. Fig. 4 is a vertical section of the same, the line of section shown in Fig. 3 at a. Fig. 5 is a front view of a modification of its door. Fig. 6 is a horizon. tal section of one of the re-box pieces or cylinders.

A represents the bottom or foot plate. It is made circular for round stoves, as shown, according to the peripherical form of the stove. It has a bottom rim, which has dovetail-shaped slots or grooves, to attach its legs B B. Its upper surface is formed with three tiers of seats or elevations, O, D, and E, of which the top elevation, O, has a periphery, to vreceive over it the ash-piece F. -Over the secondary elevation, D, is fitted a sheet-metal cylinder or air-flue, G, and over the periphery of the lower elevation, E, is ttedthe exterior sheet-metal cylinder or mantel H. By means of small screws, rivets, or boltsl I passing through the said elevations and the bottom ends of said mantel H, flue Gr, and ash-pit F, the same are secured solidly to said foot-plate. The ash-pit piece F is formed with a throat, J, the aperture of which is provided with a sliding door, K, which is fitted over it to close nearly air-tight, and is hin ged and attached to the top edge of said throat, in manner to allow it to slide partly oil or entirely over the opening `ot' said throat,

` or that it may be tilted up entirely oft' the said opening. In the upper part of said piece Fis 'said "opening when said door is tilted up, and

it rests with its opposite edges on shelves or on projections MM formed on the inside of said throat, as shown in Figs. 1 and 4. The top Y part of said ash-pit piece is formed with an inward-projecting ilange, N, and with a socket,

O, above it, into which the bottom edge of the irebox I is received. The object of the ange N is to stop and hold the bulk of the coal above the grate, to permit the air to pass freely through the coal to the re. The fire-box is constructed of several short cylindricalshaped castings, each with a number ofequallyw-distributed vertical ribs or corrugations on i'ts outer periphery, as shown in Figs. 1 and 6, and each with a socket, Q, like that ofthe ash-pit piece, to receive the above or succeeding piece or casting, so that they all may be'ready mounted and cemented in their joint, or may pack themselves by the accumulation of ashes in said joints. Intthe socket of the upper casting is fitted the top piece R of the lire-box, which has also a cylindrical form, but has its top formed with a closed cap or top, S. Below said cap the same is made with a round throat, T, projecting horizontally toward the rear, and suitable in diameter and length, to receive the smoke-pipe of the stove; and toward the front it is made with a square or oblong inclined throat, U, which has a proper dimension for supplying the stove with coal. Said throat has a door, V, in front of its aperture, which is tted nearly air-tight upon the edge of said throat; and it is also hinged, similar to the door K, before mentioned. The bottom plate A has a series of perforations, W W, on each of its seats E and D. The ue G extends up along the re-box P until reaching the top piece R. The outside mantel H is sufficiently high to reach above the entire top of the rebox, and has a perforated cap, X, over its top.

When the stove is used as a heater, to distribute the heat over several rooms, or heat large rooms, so as to require heat-conducting pipes, its cap X is substituted With a drum,Y, (shownin dotted lines in Fig. 1,) from which drum the requisite hot-air pipes lead to the rooms, halls, or places to be heated.

Instead of the door K being made to slide,

to regulate the draft and heat of the stove, there may be a register-plate attached in front of said door, to answer the same purpose, as shown in Fig. 5.

When the stove is first or newly ired the door K is opened, the grate L properly placed, the door V is also opened, and through the throat U the stove is filled with coal up to within a short distance of the throat T. A small quany tity of wood is placed thereupon and set on lire, and at the proper time a small quantity of coal placed over the wood. The door V is thereafter shut tight. Through the door K sufficient air is admitted to perform proper combustion, and to slowly burn the coal from the top down, so that the stove does not need feeding or supply for twenty-four hours. By means ofthe door V the stove may be supplied to continue its lire. The cold air from the room passes under thefoot-plateA and through its perforations W, as shown by the arrows in Fig. l; and it passes rapidly between the cylinder or iiue G and the fire-box P, and also between said flue and the mantel H, sufficiently absorbing the heat and cooling the tire-box to prevent its becoming red-hot, and to prevent the formation of carbon-oxide gas, which is objectionable to the health. The heated air passes through the cap X into the room.

By the said rapid current of air passing the stove and into the room, the whole temperature ofthe room is soon equalized and raised.

The stove can be placed in close proximity to furniture without danger of setting on fire the same, as its outside mantel H does not become suiiiciently heated for that.

The top portion of the mantel, above the center of the throat T, is made of a separate piece, or detachable, to allow the top piece R to be placed before the mantel is closed. y

The stove may be closely packed by taking it apart, and can be mounted by entirely inexperienced persons.

Having fully described my invention, what I claim therein, and desire to secure by Letters Patent, is-

1. The ashpit piece F, with the flan ge N and socket O, and the grate L, in combination with the fire-box P, substantially as and for the purpose herein stated.

2. The foot-piece A, constructed with the seats C, D, and E, and with perforations W, in combination with the ash-pit piece F, the mantel H, and ilue Gr, all constructed substantially as and for the purpose herein mentioned.

In witness whereof I hereunto set my hand this 25th day of' February, 1874.

EDWARD PALMIE.
